Machine for winding coils

Abstract

A machine for winding coils comprising at least one support frame, a belt having a closed-ring configuration installed on the support frame so as to substantially surround it peripherally, and a platform on which the at least one support frame is positioned. The platform is provided with support elements configured to selectively support the at least one support frame in a distanced position with respect to the platform. Actuation members are associated with at least some of said support elements, and are able to be selectively activated to take at least some of said support elements to a first operating position constraining the support frame to the platform, and to a second non-operating position of non-interference with said support frame.

The invention claimed is: 
     
       1. A machine for winding coils comprising at least one support frame, a belt having a closed-ring configuration installed on the support frame so as to substantially surround the at least one support frame peripherally, and a platform on which the at least one support frame is positioned, wherein said platform is provided with support elements configured to selectively support the at least one support frame in a distanced position with respect to the platform, and actuation members are associated with at least some of said support elements able to be selectively activated to take at least some of said support elements to a first operating position constraining the support frame to the platform, and to a second non-operating position of non-interference with said support frame to define an interspace between said platform and said support frame suitable for the lateral insertion or lateral removal of said belt on said support frame. 
     
     
       2. The machine as in  claim 1 , wherein said platform is provided with first support elements configured to support the at least one support frame in correspondence with a first lateral flank thereof, and with second support elements configured to support the at least one support frame in correspondence with a second lateral flank thereof, opposite the first lateral flank, and in that said actuation members are associated at least with one of either said first support elements or said second support elements. 
     
     
       3. The machine as in  claim 2 , wherein said at least one support frame comprises a support body interposed between the first lateral flank and the second lateral flank and on which said belt is installed during use. 
     
     
       4. The machine as in  claim 2 , wherein said actuation members are associated with said first support elements, and when said first support elements are in their second non-operating position, at least said second support elements support said support frame in correspondence with said second lateral flank, keeping said support body and said first lateral flank cantilevered. 
     
     
       5. The machine as in  claim 4 , wherein at least one of said second support elements is installed in a fixed position on said platform. 
     
     
       6. The machine as in  claim 1 , further comprising a first support frame and a second support frame disposed adjacent to each other, connected to each other solidly and installed on said platform. 
     
     
       7. The machine as in  claim 6 , wherein the first support elements of the first support frame and of the second support frame are installed on the periphery of the platform, and the second support elements of the first support frame and of the second support frame are installed in a central position of the platform. 
     
     
       8. The machine as in  claim 1 , further comprising a tensioner device configured to regulate the tension imparted to said belt. 
     
     
       9. The machines as in  claim 8 , wherein the tensioner device comprises a linear actuator provided with a free thrust end which contacts said belt during use, said linear actuator being configured to take the free thrust end to an active position inside the at least one support frame, and a second position, not active and completely outside the support frame, to define with the latter a free space for the insertion or removal of the belt. 
     
     
       10. The machine as in  claim 1 , further comprising a structure provided with sliding guides on which said platform is slidingly installed.
